Zinc - Essay Example But it varies with different temperatures, as the appearance becomes ductile when heated at ranges 110-150  °C. Zinc is a reactive metal that was first discovered in 1746, and the person who discovered zinc was Andreas Marggraf. The symbol of zinc is denoted with â€Å"Zn†. Being in the group of transition metals, it is the property of zinc that it conducts electricity and heat. The valence electrons of zinc are present in more than one shell. Being placed in the transition metals, it has several oxidation states. Zinc has hexagonal crystalline structure. The atomic number of zinc is 30. It has the atomic mass of 65.39 a.m.u (atomic mass unit). Zinc has a melting point of 419.58  °C and it has a boiling point of 907.0  ° C. The density of zinc is 7.133 g/cm3. The numbers of neutrons are 30 and then numbers of protons/electrons are 35. ISOTOPES OF NEUTRON: The isotopes are the atoms containing different number of neutrons and same number of protons, responsible for alteri ng total number of nucleons. There are ten isotopes of zinc that are shown in the table below. Half Life Zn-62 9.26 hours Zn-63 38.5 minutes Zn-64 Stable Zn-65 243.8 days Zn-66 Stable Zn-67 Stable Zn-68 Stable Zn-69m 13.76 hours Zn-70 Stable Zn-72 46.5 hours Zinc has two oxidation states and the valence electrons are in s shell. ATOMIC STRUCTURE OF ZINC:- The atomic structure gives us an idea about the structure of atoms and its arrangement. The atomic structure includes atomic radius, atomic size, covalent radius, cross section, and crystal structure. The atomic radius of zinc is 1.53 A °, the atomic volume is 9.2 cm3/mol, the covalent radius is 1.25 A °, cross section of 1.11, and the structure is hexagonal in nature. ELECTRONIC CONFIGURATION OF ZINC:- The electronic configuration tells us that how much electrons are placed in the specific shell. The electronic configuration of zinc is 1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s2.This electronic configuration makes the process easier to remove 2 of 4s electrons and easier to form compounds like ZnO, Zncl2 and ZnSO4.   SOURCES OF ZINC:- The annual production of zinc is 5,020,000 tons. It is found in the minerals such as zincite (ZnO), zinc blende (sphalerite) (ZnS), calamine, and franklinite. CHEMICAL PROPERTIES:- Zinc has electronegativity of 1.65 Pauling, Heat of fusion of 7.322 kJ/mol, electron work function of 4.33 eV, it has an electrochemical equivalent of 1.22g/amp-hr, and a valence electron potential of 38.9. PHYSICAL PROPERTIES:- It is hard, brittle, bluish white transition metal. The enthalpy of fusion is 7.32 kJ/mol, enthalpy of atomization is 129.7 kJ/mol, average atomic mass of 65.39 and boiling point of 907 ° C. COMPOUNDS OF ZINC:- Many compounds of zinc are formed, but ten are discussed over here. 1. Zinc Borate: It is also called as fire brake ZB. Zinc borate has elements containing Zinc, Boron and oxygen. It has a chemical formula 3ZnO. 2B2O3. Its CAS number is 1332-07-6. Its casewell number is 909b. It is white powder. 2. Zinc carbonate: It is also called carbonic acid and zinc spar. It has a formula of ZnCo3, made up of zinc, carbon and oxygen. It has CAS number 3486-35-9. 3. Zinc sulphate: It has oxygen, sulphur and zinc. The formula is ZnsO4. The CAS number is 7733-02-0. Casewell number is 927. It is also called Bonazen having several other synonyms. 4. Zinc chloride: Is formula is ZnCl2. It has elements containing zinc and chlorine. Its CAS number is 7646-85-7. Its casewell number is 910. It is also called as butter of zinc. 5. Zinc Oxide: It has elements zinc and oxygen. Its chemical formula is ZnO2. Its CAS number is 1314-13-2. It casewell number is 920. It is also called as snow white. 6. Zinc stearate: Its formula is Zn(C18H35O2) 2. It has carbon, nitrogen, oxygen and zinc. Its

History of Bacteria, Penicillin and Germ Theories

History of Bacteria, Penicillin and Germ Theories Mursal Malekzadeh THE GERM THEORY How this all began was before the germ theory was developed. Edward Jenner who was a doctor came up with vaccination. Smallpox was popular in the 18th century and so many people died due to the smallpox. Girls who would milk cows didn’t catch smallpox but instead caught cowpox. There was no research into disease and infections in the 18th century. Edward Jenner thought of an idea. He thought that people could be protected from smallpox if he would inject them with cowpox so therefore in 1794 he tried this idea which proved his prediction right. Also to provide clear evidence he injected a smallpox victim into the same person he injected cowpox with 2 months after. This caused the person to show no signs of smallpox because he had been injected with cowpox previously. Jenner’s idea became widely accepted as it cured a lot of smallpox victims. Jenner’s technique of injected cowpox into smallpox victims is now called vaccination. In the 1980s the world health organi sation suggested that the disease didn’t exist anymore due to an international vaccination programme. This got rid of smallpox. Although Edward Jenner’s theory was correct and there’s evidence to prove it but his technique would not be permitted today because its considered unethical to use healthy participants and inject them. In the 18th and 19th century many women who just gave birth were dying within 5 days of their delivery. There were clear symptoms such as vomiting and inflammation of the womb however no one knew why this was happening. Ignaz Semmelweiss was a doctor who worked in the maternity wards. Semmelweiss found out that his medical students would straight away dissect a dead body to delivering a baby without washing their hands. This made him think if they had the cause of the disease on their hands from the dead patients previously to their pregnant patients. Semmelweiss knew that the deaths were caused by an infectious agent so therefore he told all his medical students to wash their hands in soap before they went to the maternity ward. This was effect because the death rates dropped to 1% after 2 years. On the other hand other doctors wouldn’t agree with Semmelweiss idea because they thought the pain women received after childbirth was due to god punishing them. Washing hands in the 19th century was hard because there wasn’t always running warm water and the soap made of chlorinated lime would damage the hands but today everyone washes before and after they do anything. Later in the 1920s Alexander Fleming discovered Penicillin. He noticed a lot of mould on his plates after he came back from holiday. One day he used mould juice which he called penicillin but the problem was that he couldn’t get a lot of mould juice because it would go bad so this made him stop doing experiments to prove if penicillin would kill bacteria. In 1938 Howard Florey and Ernst Chain did further research into penicillin. One of their experiments were based on 8 mice which they injected 4 of them with bacteria that would kill them and 4 with penicillin. The results showed that the 4 injected with penicillin survived whereas the other remaining 4 died. They could prove that penicillin destroyed bacteria. The next problem was making enough of it for everyone so they went to USA with their mould and the big chemical companies helped them make penicillin. Penicillin is very popular today as it has been used by many to destroy bacterial infections. All these past events influenced Pasteur to come up with the germ theory. The germ theory of disease is thought that infectious diseases are caused by a germ. Louis Pasteur who was a chemist and biologist did a lot of research into the germ theory. In order to help him with his experiments people such as Robert Koch developed the microscope so that microorganisms were visible. Pasteur had an idea that growths that developed like mould on food, were from microscopic organisms which were in the air. Pasteur did some experiments to see if his prediction was correct so he boiled broth and closed the container and it would be clear however when he added other things that were exposed to the air, he saw that microorganisms developed in the broth which caused it to be cloudy. He repeated many more experiments until he came up with a series of experiments which used swan necked flasks because this proved that microorganisms that appear in boiled broth come from the air. In 1845 a disease destroyed silkworms. Pasteur again knew this was due to microorganisms because it was found in the tissues of diseased silkworms, moths and eggs which were possible to see by using a microscope. Pasteur tried to get rid of the disease by identifying the eggs which were infected. This helped to save the silk industry and there was clear evidence of microorganisms causing disease. Many people died of infectious diseases but Pasteur did a lot of investigation on these diseases so therefore he developed vaccines against these diseases. Many of Pasteur’s investigations and experiments influenced Joseph Lister who was a scientist. Pasteur came up with the idea of pasteurisation which is that boiling liquid can effectively remove bacteria or germs. People thought that small organisms as germs couldn’t destroy larger ones such as humans. Pasteur did further investigation in order to explain the causes of many diseases such as smallpox, anthrax, TB and cholera. He found out that these diseases could be eliminated by vaccination and eventually will leave the body. Pasteur became very successful when he developed vaccinations for Rabies. Joseph Lister was influenced by Pasteur’s work. He was a surgeon and used Pasteur’s ideology’s to make the process of surgery more hygienic which eventually prevented many people from dying When Lister found out about Pasteurs experiments on wine going bad due to microorganisms in the air, he knew that microorganisms present in the air were causing his patients to die after they had survived surgery. This was due to the infection as the open wounds made it easier for the germs to transfer into the body. People would use carbolic acid to get rid of cattle parasite in fields so Lister thought it could stop wounds from getting infected by cleaning the patients wounds with carbolic acid as well as soaking the dressings in antiseptic liquid. Listers antiseptic surgery caused the death rate to fall to 15% but before Lister came up with his antiseptic surgery the death rate was high due to the bacteria in the air and the lack of using any antiseptic when doing surgery. Recent events that happened include the discovery of Methiciliin in 1960 in order to treat infections caused by bacteria resistant to penicillin. In 2008 the cervical cancer vaccination programme was developed and introduced in UK. It was suggested to vaccinate girls aged 12 against HPV. 3 vaccinations are given every six months. This vaccination helps to protect against types of HPV. In conclusion all these events tell us that vaccination is very effective so therefore ever since vaccination was first discovered it has been successful.

Art Therapy: A Necessary Tool for Success Essay -- Art

Art is the self-expression of someone or something that shows the hidden or underlying emotions upon which are found within the unconscious mind (Merriam-Webster). Art can tell stories of past events which were significant to that culture or person. This could include things such as hunts or sacrifices to please the gods. As society and people started to evolve and become more and more like modern day society, so did art and how society viewed it. At the beginning of the renaissance in Europe, many new artists and ways of thinking began emerging which soon became the mainstream way of thinking. Artists from this time period transformed art from what it was to how we view it today. From being a tool to tell stories with, art slowly started to shift to a more abstract way of thinking. As people and their minds started to change, how we view art and the uses of how art became limitless. When someone talks about art, there are many different aspects that they could be talking about. Art could be a simple painting but it could also be an elegant sculpture or sketch. When thinking about art and the uses that art can have the possibilities are endless. Art could be used as self-expression of suppressed feelings that are unknown to the conscious. Art is looked at as a good way to relieve stress and express emotions. It was not until art was seen as something more than decoration that it became a form of therapy that could be used in our everyday lives. Art therapy is a very useful and effective therapy tool while treating kids and young adults with ongoing issues involving both emotional and or psychical damage.

I Believe in Forgiveness Essay

I never really understood the meaning of forgiveness. When people hurt me or treat me badly I always thought the best way to handle it is to hold it in. I never showed anger on the outside but just kept it all in. Instead, I let it boil inside of me. My kind act toward those who hurt me was a shield from my pain. Most of my kind act was at my mother. I blamed my birth mother for every relationship I have ever been in that ended with my hurting the guy or me thinking I am just going to be like my mother and leave him for the next person. see more:to err is human meaning Over the years, her actions and mishaps became the victim for my own actions. The fact that I have not yet become a divorcee like her was justification for her being irresponsible, dishonest, and ungrateful. Throughout the years of struggle, dysfunctional relationships, and little to no relationship, I hardly took responsibility for anything that I had done. I laid all my relationship troubles on my birth mother. I call her my birth mother because I never grew up with her but I have met her from time to time. She gave me to my dad when I was seven years old because of another man. I blame my relationship trouble on her because she never had a solid relationship for me to learn from. She has been married four times and the longest have been a year and that was to my dad. Then a few months ago, something shocking happened to me: I was in a committed relationship for the first time in my life. I was so scared I would be just like her or I was going to ruin this wonderful guy’s life. One night, as I was trying to sleep, thinking about my life, I suddenly became filled with fear. I was convinced I would screw up my life —that all my fear of being like her was tarnishing my relationship life. Strangely, while panicking about my life becoming a doom, my mother came to mind. I sat there in the dark, surrounded by the soothing sounds and smells of my air freshener in my room, and I thought of how my mom must have blame her mother for the same reason I am blaming her. I knew at that moment that she never intended to hurt me. I realized that might have been as scared like I am when it comes to commitment just as I am. I knew that she had done the best she could to stay in those relationships, but it was not the right thing to do. I forgave my mother that night—for all the times she got divorced, embarrassed me, or hurt my father or made me feel like I can never have a relationship because I always think I would end up like her. I forgave her for not being around. I let go of the resentment I’d held toward her for so many years. I stopped blaming her. For some reasons maybe my reasons were not very noble. Maybe I was afraid my life would turn out to be just like hers or maybe I might never find that person to settle down with. Whatever the reason, for the first time, I saw my birth mom as a real person. A person with flaws and mistakes. I knew she did not jump from marriage to marriage to hurt me. She got divorced for four times because she was flawed and hurting. I knew that if I did not forgive her, I would never have the kind of relationship I wanted with my future husband. If I kept blaming her I would never start living my own life. My mom have not asked for my forgiveness; she’s never acknowledged that she’s done anything wrong. But I realized that in forgiving her, what I was really doing was taking responsibility for myself and my own actions for the first time in a long time. Forgiving my mom changed my life. I accepted her for who she was and that set me free. I realized that when we forgive someone it is not for them but for you. After I forgave her it was like a burden was taken off my shoulders. I felt this inner peace that I have never felt before. My relationship with my boyfriend is going good and I don’t think or say to myself that I am going to end up like my mother. My eyes are open now to my own failings. I am going to take responsibility for every mistake I make in my relationships and not blame someone for them. And I discovered that forgiving someone is both an innately spiritual act that brings us closer to a higher power, and a uniquely human act that connects people in a way that strengthens us all. Forgiveness is a powerful thing. This I believe. I Believe Essay Draft 1 09/12/12 Word Count 752 The Power of Forgiveness I believe in forgiveness.

Compare and Contrast Readings Essay

You have suffered before as I have suffered, maybe not exactly as me, but you have experienced a type of suffering. Mary Rowlandson shows us what suffering is in her book called â€Å" A Narrative of the Captivity,† by creating a character who loses her six year old child due to an attack in her town Lancaster and constantly being moved. Another author, Olaudah Equiano, writes a story about another type of suffering in his book â€Å" The Interesting Narrative of the Life of Olaudah Equiano,† by telling readers about him being kidnapped directly from his home and being brought into slavery. By reading these excerpts readers can see different types of suffering and how the characters handle them. â€Å"The Interesting Narrative of the Life of Olaudah Equiano† articulates suffering better because there are events that most people would know about and tells how people around him are dealing with the changes. Equiano’s narrative takes place in the 1800s, when slavery started to become popular. He talks of his self becoming a slave when he was just a kid. After, serving as a slave for different people in Africa, being detached from his family, and getting shipped off to stay a slave but in a fortune country, he did not become belligerent. â€Å"I did not know what this could mean, and indeed I thought these people were full of nothing but magical arts,† (Equiano 59). Equiano thinking the men that are about to enslave him are full of magic proves how young he is, too young to be a slave. A child being a slave for the rest of his or her life is a horrific way to spend one’s childhood. He has suffered all of his life, beginning with the day he was taken away from his home but after all this he did not seek revenge, he became an author. Rowlandson’s narrative speaks on the American Indians being removed from their native land by English people. When a reader starts reading the excerpt, one might think it is only about a woman losing her children but  once you look at the details you will see how the events she describes relate to the event of Americans kicking American Indians off their land. â€Å"The occasion (as I thought) of their moving at this time, was, the English army, it being near and following them†¦Ã¢â‚¬  (Rowlandson 39). The reason why readers did not know of the event from the start of the story is because the main character did not know why either. The quote gives us confirmation that the moving to different places is because of the â€Å"English army,† Americans, taking over their property . Both of these authors did a great job at helping readers view different types of suffering and how people handled it. Mary Rowlandson, the main character handles the suffering of losing her children and her home by staying connected with God, as I would. Olaudah Equiano, the main character of â€Å"The Interesting Narrative of the Life of Olaudah Equiano,† suffers by getting stolen from his home and brought into slavery. By looking at how Equiano deals with being a slave, it is like he just accepts what is happening and does not try to change it. Although Olaudah Equiano does not do much to change his life as a slave, he does a better job at explaining his sufferings to a point where people can relate or know a little background of the event.

EMVC Essay Analysis done final

EMVC Essay Analysis done final EMVC Essay Analysis done final On the wall of Santa Maria delle Grazie in Milan, Italy, is the world widely renowned renaissance fresco by Leonardo Da-Vinci; The Last Supper (Tempura on gesso, pitch, and mastic 460x880cm). Da-Vinci was an artist, scientist, architect, author, engineer, inventor, and humanist, who perpetuated the confluence between Renaissance ideology and artistic commerce, living from 1452-1519.1 The Last Supper is a large fresco like piece on the side of a wall in a dining hall of the delle Grazie’s adjacent monastery, though not a true fresco, as it was painted on a dry wall, instead of wet plaster. This retrogressional technique gave Leonardo more time to concentrate on the depiction of the biblical scene, being meticulous as he was, but tempted the masterpiece with ebbing.2 As commissioned by Ludovico il Moro in 1495, the piece required three years of work and was to denote the religiously polyvalent scene of Christ's last supper with his disciples.3 Da-Vinci set demarcates for religious symbology in renaissance art. Choosing himself to paint the very moment in which Christ announces that among the disciples is the one who will betray him, Leonardo connoted messages never before used in art, creating for him, a shibboleth demographic of artistic religious ambivalence in the opinion of many, which is unmatched today. Or is this that moment, as he does not look as if he has completed his sentence? The apostles are as follows: Bartholomew,James, and Andrew;Judas,Peter, and John;Thomas,James, and Philip; and Matthew,Jude, and Simon.4 Those figures closest to him appear to be recoiling in dismay at what they have heard, or are about to hear, whereas those further at the ends of the table seem as if the words have not yet reached them. Furthermore it becomes evident that it is not a single idiosyncratic moment, but a conveyance of a sequence of moments flowing together and forming a confluent unit, as this is applicable to other paintings of his, where human bodies and objects at certain points in space and time confound to one capricious impetus, gasconading humanity and emotion. The aspect of time is clear, as Da-Vinci has incorporated his sfumato; blending the horizon of time and movement, bringing the viewer a more realistic, prolific and life like, scene.5 He may be giving the observer a glance at his own emotional inertia towards the scene, expressed through the twelve sentinel bodies. It is evident that Christ is at the focal point of the image as his arms are spread, encompassing him into a triangular shape, expressive of the Divine Trinity. Due to the asymmetrical symmetry you can see through the copious division of bodies in groups of three and presumably the figure of Judas Iscariot to the right of Christ. These groups are displaying their personal reactions through facial expressions and movement that culminates together into one unit which suggests the spread of Christ’s words, framed by the door, from the centre to the edges of the piece, rather than standard depictions of disciples following the standard simulacrum of static presence. Da-Vinci incorporates use of perspective lines by maintaining symmetry between the apostle clusters while the geometric shapes that take form in the painting harbour the creation of the painting's dialogue.6 Da-Vinci breaks this with a baroque culmination of varied presence, confidence, movement and positioning, throug h a pluralistic medium of capricious geometric scenery. Often theories of Mary Magdalene sitting to the left of Christ in the painting are expressed, perhaps inspired by the famous Da-Vinci Code book, though rationally there is a contradiction to repudiate it as she was not a disciple, just a close friend of Christ’s.7 Although then again, Judas may not have been present, thus making twelve an accurate number, while explaining the feminine looks of the figure present. Judas in most other versions adorns the opposing side of the table. In Leonardo's, he sits on the same side

The History of the Electric Telegraph and Telegraphy

The History of the Electric Telegraph and Telegraphy The electric telegraph is a now outdated communication system that transmitted electric signals over wires from location to location and then translated into a message. The non-electric telegraph was invented by Claude Chappe in 1794. His system was visual and used semaphore, a flag-based alphabet, and depended on a line of sight for communication. The optical telegraph was later replaced by the electric telegraph, which is the focus of this article. In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering. He used 35 wires with gold electrodes in water.  At the receiving end,  the message was read 2,000 feet away  by the amount of gas produced by electrolysis. In 1828, the first telegraph in the USA was invented by Harrison Dyar, who sent electrical sparks through chemically treated paper tape to burn dots and dashes. Electromagnet In 1825, British inventor William Sturgeon (1783-1850) introduced an invention that laid the foundation  for a large scale revolution in electronic communications: the electromagnet. Sturgeon demonstrated the power of the electromagnet by lifting nine pounds with a seven-ounce piece of iron wrapped with wires through which the current of a single cell battery was sent. However, the true power of the electromagnet comes from its role in the creation of countless inventions to come. The Emergence of Telegraph Systems In 1830, an American named  Joseph Henry (1797-1878) demonstrated the potential of William Sturgeons electromagnet for long distance communication by sending an electronic current over one mile of wire to activate an electromagnet, causing a bell to strike. In 1837, British physicists  William Cooke and Charles Wheatstone patented the Cooke and Wheatstone telegraph using the same principle of electromagnetism. However, it was Samuel Morse (1791-1872) who successfully exploited the electromagnet and bettered Henrys invention. Morse started by making sketches of a magnetized magnet based on Henrys work. Eventually, he invented a telegraph system that was a practical and commercial success. Samuel Morse While teaching arts and design at New York University in 1835, Morse proved that signals could be transmitted by wire. He used pulses of current to deflect an electromagnet, which moved a marker to produce written codes on a strip of paper. This  led to the invention of Morse Code. The following year, the device was modified to emboss the paper with dots and dashes. He gave a public demonstration in 1838, but it wasnt until five years later that Congress, reflecting public apathy, awarded him  $30,000 to construct an experimental telegraph line from Washington to Baltimore, a distance of 40 miles. Six years later, members of Congress witnessed the transmission of messages over part of the telegraph line. Before the line had reached Baltimore, the Whig party held its national convention there  and nominated Henry Clay  on  May 1, 1844. The news was hand-carried to Annapolis Junction, between Washington and Baltimore, where Morses partner Alfred Vail wired it to the capitol. This was the first news dispatched by electric telegraph. What Hath God Wrought? The message  What hath God wrought? sent by Morse Code from the old Supreme Court chamber in the United States capitol to his partner in Baltimore officially opened the completed line on May 24, 1844. Morse allowed Annie Ellsworth, the young daughter of a friend, to choose the words of the message and she selected a verse from Numbers XXIII, 23: What hath God wrought? to be recorded onto paper tape. Morses early system produced a paper copy with raised dots and dashes, which were translated later by an operator. The Telegraph Spreads Samuel Morse and his associates obtained private funds to extend their line to Philadelphia and New York. Small telegraph companies, meanwhile began functioning in the East, South, and Midwest. Dispatching trains by telegraph started in 1851, the same year Western Union began business. Western Union built its first transcontinental telegraph line in 1861, mainly along railroad rights-of-way. In 1881, the Postal Telegraph System entered the field for economic reasons and later merged with Western Union in 1943. The original Morse telegraph printed code on tape. However, in the United States, the operation developed into a process in which messages were sent by key and received by ear. A trained Morse operator could transmit 40 to 50 words per minute. Automatic transmission, introduced in 1914, handled more than twice that number. In 1900, Canadian Fredrick Creed invented the Creed Telegraph System,  a way to convert Morse code to text. Multiplex Telegraph, Teleprinters, Other Advancements In 1913, Western Union developed multiplexing, which made it possible to transmit eight messages simultaneously over a single wire (four in each direction). Teleprinter machines came into use around  1925 and in 1936 Varioplex was introduced. This enabled a single wire to carry 72 transmissions at the same time (36 in each direction). Two years later, Western Union introduced the first of its automatic facsimile devices. In 1959, Western Union inaugurated TELEX, which enabled subscribers to the teleprinter service to dial each other directly. Telephone Rivals the Telegraph Until 1877, all rapid long-distance communication depended upon the telegraph. That year, a rival technology developed that would again change the face of communication:  the telephone. By 1879, patent litigation between Western Union and the infant telephone system  ended in an agreement that largely separated the two services. While Samuel Morse is best known as the inventor of the telegraph, he is also esteemed for his contributions to American portraiture. His painting is characterized by delicate technique and vigorous honesty and insight into the character of his subjects.

Definition of Interpretive Sociology

Definition of Interpretive Sociology Interpretive sociology is an approach developed by Max Weber that centers on the importance of meaning and action when studying  social trends and problems. This approach diverges from positivistic sociology by recognizing that the subjective experiences, beliefs, and behavior of people are  equally important to study as are observable, objective facts. Max Webers Interpretive Sociology Interpretive sociology was developed and popularized by Prussian founding figure of the field Max Weber. This theoretical approach and the research methods that go with it is rooted in the German word  verstehen, which means to understand, in particular to have a meaningful understanding of something. To practice interpretive sociology is to attempt to understand social phenomena from the standpoint of those involved in it. It is, so to speak, to attempt to walk in someone elses shoes and see the world as they see it. Interpretive sociology is, thus, focused on understanding the meaning that those studied give to their beliefs, values, actions, behaviors, and social relationships with people and institutions. Georg Simmel, a contemporary of Weber, is also recognized as a major developer of interpretive sociology. This approach to producing theory and research encourages sociologists to view those studied as thinking and feeling subjects as opposed to objects of scientific research. Weber developed interpretive sociology because he saw a deficiency in the positivistic sociology pioneered by French founding figure Émile Durkheim. Durkheim worked to make sociology be seen as a science by centering empirical, quantitative data as its practice. However, Weber and Simmel recognized that the positivistic approach is not able to capture all social phenomena, nor is it able to fully explain why all social phenomena occur or what is important to understand about them. This approach focuses on objects (data) whereas interpretive sociologists focus on subjects (people). Meaning and the Social Construction of Reality Within interpretive sociology, rather than attempting to work as detached, seemingly objective observers and analyzers of social phenomena, researchers instead work to understand how the  groups they study actively construct the reality of their everyday lives through the meaning they give to their actions. To approach sociology this way is often necessary to conduct participatory research that embeds the researcher in the daily lives of those they study. Further, interpretive sociologists work to understand how the groups they study construct meaning and reality through attempts to empathize with them, and as much as possible, to understand their experiences and actions from their own perspectives. This means that sociologists who take an interpretive approach work to collect qualitative data rather than quantitative data because taking this approach rather than a positivistic one means that a research approaches the subject matter with different kinds of assumptions, asks different kinds of questions about it, and requires different kinds of data and methods for responding to those questions. The methods interpretive sociologists employ include in-depth interviews, focus groups, and ethnographic observation. Example: How Interpretive Sociologists Study Race One area in which positivistic and interpretive forms of sociology produce very different kinds of questions and research is the study of race and social issues connected with it. Positivistic approaches to this are of study tend to focus on counting and tracking trends over time. This kind of research can illustrate things like how education level, income, or voting patterns differ on the basis of race. Research like this can show us that there are clear correlations between race and these other variables. For example, within the U.S., Asian Americans are the most likely to earn a college degree, followed by whites, then Blacks, then Hispanics and Latinos. The gap between Asian Americans and Latinos is vast: 60 percent of those aged 25-29 versus just 15 percent. But these quantitative data simply show us that a problem of educational disparity by race exists. They dont explain it, and they dont tell us anything about the experience of it. In contrast, sociologist Gilda Ochoa took an interpretive approach to studying this gap and conducted long-term ethnographic observation at a California high school to find out why this disparity exists. Her 2013 book,  Academic Profiling:  Latinos, Asian Americans, and the Achievement Gap​, based on interviews with students, faculty, staff and parents, as well as observations within the school, shows that it is unequal access to opportunities, racist and classist assumptions about students and their families, and differential treatment of students within the schooling experience that leads to the achievement gap between the two groups. Ochoas findings run counter to common assumptions about the groups that frame Latinos as culturally and intellectually deficient and Asian Americans as model minorities and serve as a fantastic demonstration of the importance of conducting interpretive sociological research.

IT and facilities functions by Schwartz - Essay Example However, these systems are of no use to facilities management team. Ironically, facilities management holds the responsibility of costs saving, of which energy saving is a critical practice and core area where costs can be saved. Energy consumption is the maximum in the data center, as explained by Schwartz (p.1). Role of IT in facilities management has bee highlighted throughout the article. Considering that data center consumes maximum energy, the virtualization technology helps in minimizing the number of servers required. Energy-saving virtualization technology is one reason IT is getting involved in energy infrastructure management (Schwartz, p.1). However, this system could be risky if the server fails. Here, facilities management comes into picture, which can help by involving in management of the data center. For this, the facilities manager should be equipped with IT working skills. Sharplin, the CEO of Site Controls, emphasizes the need and benefits of IT in facilities mana gement in the real estate industry, which include lower costs of energy, decreased equipment maintenance costs, reduce carbon footprint and increased efficiency (Schwartz, p.2). In this article, Schwartz clearly underpins the significance of involvement of facilities managers in IT functions and/or have substantial knowledge of IT that can be implemented for successful facilities management and cost-saving practices. Indirectly, Schwartz also indicates that facilities management can be accomplished by using sophisticated IT systems; this would require facilities managers to be equipped with IT skills and understanding. This process would also require successful integration of facilities management and IT infrastructure. Integration between these two functions would again mean that facilities managers obtain a thorough understanding of working of IT systems.

3. Biomaterials for bone tissue-engineering - Essay Example Osseointegration means the ability to integrate into surrounding bones. The ideal condition is that the tissue should be reabsorbed and may be even replaced by the body’s own regenerated biological tissues. Bioactive inorganic materials like tricalcium phosphate, HA, bioactive glasses have a large capacity to be re-absorbed. This is definitely one of the positive points of inorganic materials. But the main problem is their brittle nature. This brittle nature means that the fracture toughness of the bones cannot b matched by these materials and thus is not ideal for picking heavy loads. Polymers such as collagen and hyaluronic acid are polymers which are interesting options for the use (Seeherman H, 2008).However they have weak mechanical properties and provide a possible risk of diseases if there is poor handling. Hydrogels are the kind of polymers which are creating great buzz about their use. They have many advantages including the one that chemical biofunctionalisation and cell encapsulation and delivery are very straightforward. In order for the biomaterial to be like a real bone the toughness of a polymer needs to be combined with the compressive strength of an inorganic material (Hollinger, 2004). This improves their mechanical properties and degradation profiles. Once the adequate biodegradable polymer has been selected the next step is to find a suitable processing technique. The processing methodology must not adversely affect the biocompatibility or the chemical properties of the chosen materials. Through the years a variety of processing techniques have been developed. Some of them will be discussed here by us. Solvent casting /Particulate Leaching – This method consists of dispersing calibrated materials such as sodium chloride or organic materials like saccharine particles in a polymer solution. The dispersion is processed after this either by casting or by using the method of freeze drying which results in

Increasing Literacy and Reading Competency of a Four-Year Old Learner - Assignment Example appraisement, educational adjustment profile (EAP), specialist report, assessment - minimum 3 types, research literature - minimum 4). 2. Use positive language to highlight what the student can currently achieve. Do not use a deficit approach. Avoid comparisons with the norm. I am particularly interested in finding out about the student's interests, likes and dislikes and learning characteristics. What do you already know about what works for this student Melanie (pseudonym name) is a healthy four year-old girl, currently attending K1 in Modern Montessori International Group (MMI). Through the use of appraisement observation (Wood, 1992), it has been noted that when she is asked to read a selection and later on asked of what she has understood about it, she loses track of the entire reading subjecting her to forgetting even the simple words that she has already come across within the reading. Besides that, it could be noted too that even though she is asked with regards the meaning of the words that she was already given familiarity to while reading the material given to her, she has the hardest time remembering them during the first time of questioning. If closer observance is paid to the reading process of Melanie at home, it would likely lead to different end results, as per suggested by the Educational Adjustment Profile (Balasundarm, 1998). If one lets her read a line that includes very simple words that she already knows or has come across earlier, there is no reason why she could not finish the task. As for a fact, she will readily do the reading from the beginning of the text as required continuously up until the end of the reading piece. However relating the different meaning of the words in the reading becomes a hard matter for her to complete. Through the use of one-to-one assessment method (Steven, 2008), I, as the teacher of Melanie, was able to observe her different developments based from the number of practices and trainings that she has undergone such as phonics, reading comprehension and other word based programmes that are all aimed to help an individual verbally comprehend with written pieces of reading. Through a systematic process of gathering the data I was able to keep a record on how well my niece is making improvement based from the daily activities that I handle with her in a regular basis. I used both formal and informal assessments to ensure that the Melanie is making progress. This means that the assessment could happen during or even after classes (ASHA, 2009). Through this mandated procedure, I am sure to be able to help Melanie enhance her skills on understanding words and their context even after class allowing her to see things in a practical manner. As noted through the said observation I learned h ow my niece has become much patient and perseverant in accepting the lessons I present to her making her better acquainted with the lesson thus pushing her to develop further in her learning.

Every business project is profit oriented and returns on capital employed stand as the main goal. That is why I consider that Finance perspective should focus on the cost control to ensure that in the long run income is more than the input. In a business process, the steps of what to do are provided to ensure that the end goal of profit making is achieved. It works with a target of minimizing cost so as to maximize returns. The ways of cost minimizing are wage cutting, reduction of advertising cost and reduction of employees. This is the level of deployment of the best practices an organization has defined for its Project Management process (Galliers & Leidner 2003). A lot of collaborative tools have to be designed in order to reach the recommended standard of Capability Maturity Model Integrated, a best practice framework for businesses dedicated to product development (Galliers & Leidner 2003). This part work with a clear set framework that covers areas like objectives, measures, target, and initiative. This gives everyone in the system a guide on what to do and the target goal is always indicated. For this case of study, I can bring out the best framework of a balanced scorecard as below. A balanced scorecard is used to evaluate the performance and future improvements of an organization. "Scorecard" signifies quantified performance measures in the process, financial performance, internal process, customers and learning, and growth. Balanced is an indicator showing if the system is balanced between short-term objectives and long-term objectives, financial measures and non-financial measures lagging indicators and leading indicators and internal performance and external performance perspectives (Goodpasture 2010).

Analytical Paper Essay Example | Topics and Well Written Essays - 1250 words

Analytical Paper - Essay Example Via the characters they come across on their mainland trek, Granado and Guevara witness personally the injustices, face the deprived as well as meet the people and social-classes they could have never came across before. To their astonishment, the road portrays to them a real and enthralling image of Latin-American identity. Consequently, the trip correspondingly establishes the beginning of cognitive dissension and revolution within Guevara Ernesto, who apparently would later consider armed revolution as a technique to confront the continent's widespread economic disparities (Drinot17). In Cuba, Guevara discovered that the peasants had no electricity, schools, accessibility to healthcare and that 40% of the grown-ups were uneducated. Guevara established workshops to impart military tactics, health clinics as well as a newspaper for information disseminating. Guevara was instrumental for devising novel strategies for Cuba’s political, social as well as economic development. Gu evara ensured revolutionary justice against the traitors; he also instituted the Agrarian land-reform as well as the Agrarian Reform Law. This resulted in land redistribution and equality. Guevara was instrumental in instituting universal accessibility to higher education through introducing ‘affirmative action’ to institutions of higher education (Elena 45). Guevara is portrayed in The Motorcycle Diaries as a first-timer tourist:  a freshman finally wriggling out of his upperclass bubble and understanding the world as it is.  Eduardo Elena’s article â€Å"A  Point of Departure† contests this by indicating that this was not Guevara’s first voyage (26). In the movie, Guevara tells Granado that he had not traveled before, though Elena articulates that Guevara’s upper middle-class social rank gave him the chance to travel on holidays with family, and he  travelled as a youth before getting on this specific expedition. Elena  emphasizes that it is this tour in all over South America that is broadly thought to have opened Ernesto Guevara’s eyes to the miseries of the publics as he departed from his accustomed life in Argentina from  1951 to 1952. Guevara’s trips had him witness the divide between the haves and the have-nots (Drinot 10). The Motorcycle Diaries portrays Guevara persistently disregarding his fortunate social status to go through his explorations as an ordinary person. Elena supposes that this transpired as one approach in which Guevara started to display his non-conformist outlook towards a conventional community; his non-conformist explorations had a reflective impact upon how Guevara viewed the society around him.  Ernesto had the aptitude to decide to  rough-in, and this provided him with a distinctive perspective  to see the  predicament of the underprivileged he came across on his explorations (Drinot 11). Guevara’s discoveries made him have a negative attitude towa rds the prevailing upper and middle class standards, cultural expectations, as well as the political tendencies of the 50s. Elena states that  this was Guevara’s choice,  as demonstrated many times  in the movie through his endeavors to interact with the common people they came across in their exploration rather than renting home services or lodging (34). While Granado sought to exchange their skills for food and shelter, Ernesto

Silkwood Essay Example for Free

Silkwood Essay Silkwood took a big risk when she decided to blow the whistle on Kerr-McGee in 1946 for health and safety violations. Silkwood was concerned about her and her coworkers’ health and safety as she witnessed various health and safety violation acts that management ignored. Whistle blowing can be very dangerous for the one that is blowing the whistle as witnessed by the mysterious death of Karen Silkwood on the night of November 13th. Up until her job with Kerr – McGee, Silkwood lived a normal life and didn’t do anything in her life to make her stand out. It wasn’t until her investigation began, that Silkwood was starting to become more noticeable. According to friends that were close to her, Silkwood became more and more involved in the investigation and wouldn’t let the investigation go until all evidence and facts had been reported. However, Silkwood’s evidence and findings never did make it to the appropriate people due to the mysterious car crash that led to her death. Officers and scene investigators never did find the manila envelope containing the evidence, but Silkwood’s death brought to light the seriousness of the investigation and eventually, the closing of the Kerr-McGee Cimarron plant where Silkwood was last employed. While there are many rewards to whistle blowing, there are also many risks to whistle blowing as well. One of the rewards of whistle blowing is that the laws or acts being violated will be corrected by the correct regulation agencies. Whistleblowers are even able to submit a confidential report online through National Whistleblowers Center website where attorneys review the information and give advice on the best ways to proceed with the investigation. There are also information and additional resources available for those who are thinking about blowing the whistle on their company. A risk of whistleblowing on the company can lead to alienation between the whistleblower and their employer, boss, and co-workers. Some may fear retaliation if seen helping those gain evidence against the company or organization practicing unethical practices. They may also lose their job by blowing the whistle and family and friends may also be affected by the act as well because of their relationship to the whistleblower. As employees, it is our responsibility to protect the company or organization values while at the same time, also following our own moral values as well. Every company and organization has their own morals and values that they established, but if an employee witnesses or comes across evidence that does not uphold those values, than the employee has a responsibility to report those unethical practices. Employees also have their own person moral values that they usually use as standards when finding a company or organization to work for. When dealing with unethical practices, an employee bases their decision to report the company against their own personal moral values. It is than the employee’s responsibility to make that tough decision on reporting their company’s unethical practices and risking everything or leaving it up to someone else to make that decision.

Essay --

Shusanta Bhattarai Ms. Kelley Formal lab report The conservation of Mass and how it’s connected to chemical reactions Introduction In this lab, we were looking at the conservation of matter, chemical reactions and using mass to find the number of moles present after a reaction. We had previously studied moles (measurement system) and mass. We copiously took notes on the masses of the objects after reactions and observed how the quantity would â€Å"change† after a chemical reaction. The conservation of mass is a law that states a mass will stay consistent over time and will not change until it is not combined or removed. We performed a lot of chemical reactions in this lab. The first part of the lab was putting a coiled piece of copper in silver nitrate and washing it out with water. The second and third part was also about adding chemicals and seeing the reactions. The purpose of the experiment was to determine if the values of silver and silver nitrate would stay the same. The hypothesis was that if chemical elements and compounds react the ratio would stay the same, due to the conservation of mass and the law it has. Procedure Originally, I was supplied with 30 cm of copper wire and a test tube. First, the wire was cleaned with steel wool.The copper wire was coiled around the full length of the test tube. The copper was then weighed. Then an empty 250 ml beaker that was labeled by my partner was weighed. A vial of white silver nitrate was also weighed. After, 2/5th of the clean beaker was filled with distilled water and the solid silver nitrate was stirred in with the water until the crystals that were formed dissolved. Then the end of the copper wire was bent so we could submerge the coil in the solution and still be able t... ...s is attached and the mass must remain consistent over time. The chemical process did not change the quantity and it showed. 4. The ratios might be different because there might have been a flaw in the procedure. They all still surround 1 and no one in the class got one but we all got something close. 5. I think that the decanting process was the main source of contamination. Sometimes water doesn’t take out all the specks. We could buy a high tech decanting type-system and walk through each student individually so that there would be minimal chance of error. Conclusion We saw that no matter the chemical change we would get the same ratio. The purpose worked out in a great fashion and showed us that the quantity was almost the same. The whole class got a number that was close to one. The hypothesis was supported because the conservation of matter proved to be true.

The research was compiled in three bunchs of statements: benefits for society, for the instruction business and for the infant pupils. This first statement declares that with an increased figure of males in the instruction profession that there would be an altered attitude to premises in relation to gender functions and duties. This is briefly conveyed ( Cameron & A ; Moss 1998 ) that differentiates between male and females in relation to childcare – contradictory of sensed stereotypes. Additionally, the following bunch argues that with more male input in the profession there would be an addition in the position and of instructors ( Lyons et al. , 2003 ) and besides would better workplace kineticss and staff interrelatednesss. Besides there is grounds that supports work forces keep higher paid administrative places that could potentially be transferred to the learning profession. The 3rd statement is that work forces can assist develop kids ‘s attitude for a diverse hereafter. By exposing kids to non-traditional buildings they can get down to go more compassionate and morally right.Sternod, B.M. ( 2011, Issue 2 ) . Role Models or Normalizing Agents?

This diary identifies adult females as a menace to the development of immature males as they override the masculine impact that is attempted to be conveyed. Evidence supports the deficiency of male instructors in simple schools with merely 9 % being male. Some school kids have no male influence in their lives and urgently necessitate an influential figure to larn and draw a bead on from. Male instructors besides supply concrete subject within the schoolroom but besides can understand immature male behaviorism. Males are besides, more austere doing kids more alert within the schoolroom and they besides are able to link with pupil, in bend bettering acquisition. Michael Gurian ( Hein, 1998 ; Peterson,1998 ) claims that male childs learn through a â€Å" masculine nurturing system † which revolves around â€Å" regard. Male childs can derive regard from an older/wiser male and this has to be earned. If a male child acts unsuitably the higher ranking male will loss regard for that person and it is up to the person to accomplish it back. This relationship has a inclination to be around males – therefore it would be good for male influence to be in school community. Lack of male influence both in and out of school physiques up a inclination for Acts of the Apostless of force and other offenses. Without a powerful influence in a kid ‘s development their natural maleness is free to make what it wants. Without positive counsel immature male could easy fall in to the incorrect paths and may non hold good ethical motives and could arise against what is really good. This diary continues to look at different facets of what makes a function theoretical account and what it has been based on.Lexis Nexis UK Newspaper database articleClark, L.

Within these statistics 61,060 of the pupils are having free school repasts due to low income – highlighting that the job is countrywide. There is a deficiency of male influence within primary students taking to claims that excessively many male childs are holding small or no interaction with males before making high school. With a altering nature within places there potentially may be pupils who reach early maturity and holding no male influence – making a ‘distorted ‘ position of society. Professor John Howson at Oxford Brookes University agrees stating: â€Å" If you ne'er acquire a opportunity to interact with one gender, so you are non acquiring a rounded instruction † .

This article was produced by a pupil at an American University who was bring forthing an Action Research Project on the deficiency of male instructors in a schoolroom. The survey identifies that the National Education Association ( NEA ) , revealed that less than one-quarter of all instructors were male. Recent surveies show that the deficiency of male instructors is due to low wages and issues associating to gender stereotypes. The paper is garnering research on the deficiency of a strong male function theoretical account in schoolrooms holding a harming impact on a kid ‘s sustainable development. Male instructors are viewed as function theoretical accounts ( Martino, 2008. p.192 ) . â€Å" Recuperative Maleness Politicss † are a agencies to change stereotypes and convey back a male influence into the schoolroom. This is significantly of import for immature male childs as they look for a function theoretical account, person to draw a bead on to. Gender besides plays an impact on schoolroom direction techniques which differ from male and female. Males within a schoolroom have a better impact in relation to females as kids respond to bids from a male more instinctively ( Kesici, 2008 ; Bryce & A ; Blown, 2007 ) . The article continues to detail the sum-up of the pupil ‘s research and his program of what he is traveling to make to garner relevant grounds.Andersonian library BookJames, A.N. ( 2007 ) .

This book analogies ‘ that maleness is an indispensable facet of a kid ‘s development – kids should be able to see that there are many alternate ways of seeing the universe from a gendered position. Male function theoretical accounts are critical: with many an increasing figure of one-parent households a dominantly female influence disenable male childs to specify what it means to be a male child ( Neall, 2002 ; Pollack, 1998 ) . A job arises with a chief female influence on a immature male: what if in seeking to move like a male, a child Rebels against the influence of a female and acts the complete antonym. He may hold decided that the right behavior for work forces is ill-mannered, angry, noisy and vocal. This acts as a cardinal defect to a feminist position within a school environment ( Mac and Ghail, 1994 ) . A male instructor can besides impact originative subjects such as art in a positive mode. By giving the kids a mechanical point of view the pupils took it in on their pace and completed a undertaking as holding thought about it alternatively of a stereotyped female originative expressional side. The book is all about the manner boys learn and how they can be influenced and taught in different ways.Online Library ArticleBittner, M. T. and Cooney, M. H. ( 2001 ) .

This subdivision of the diary explores the different issues that affect work forces within a schoolroom environment. It looks at influential factors such as salary, household reaction and pre-conceptual stereotypes of being male and a member of the instruction profession. The goes on to look at the advantages and disadvantages of holding a male influence in a schoolroom. Children can profit both straight and professionally from a skilled, good educated male instructor. There are two analogies that back this up both giving grounds that male pupils have wholly altered behavior, assurance and ability with the impact that a male presence has had on the persons. Besides experiments have revealed that pupils are more watchful and concentrate on a adult male within a category – therefore would larn more. However, male instructors have a inclination to experience stray and uncomfortable being in a female dominant environment. This was besides apparent from one of the focal point groups the research workers carried out: one individual declared that some pupil ‘s parents were non happy with a adult male assisting their kids with toilet demands and another instructor disclosure that he feels judged when a kid harmlessly sits on his articulatio genus. To try to decide this ‘touch ‘ issue the group devised a procedure of constructing positive relationships with both pupils and parents in an effort to attest this issue. This article concludes by placing a demand for a declaration in the manner male instructors are perceived within the schoolroom.ComparisonSternod, B.M. ( 2011, Issue 2 ) . Role Models or Normalizing Agents? A Genealogic Analysis of Popular Written News Media Discourse sing Male Teachers. In Thiessen, D. Curriculum Inquiry. ( pp.277-286 ) . California, USA.Bittner, M. T. and Cooney, M. H. ( 2001 ) . Work force in Early Childhood Education: Their Emergent Issues. In Jalongo, M. R. Early Childhood Education Journal. ( pp. 77 – 82 ) . USA.Sternod and the Bittner, Cooney partnership both conducted research into what portion a male instructor dramas in the development of an early twelvemonth ‘s pupil. Sternod declares that there is a despairing demand for a male figure in the successful development of kids, particularly boys. The laterality of female staff overruling the really few male instructors highlights a defect in the instruction system with a deficiency of right gender stereotype instruction. Cooney and Bittner look at the learning profession and how it affects work forces. They besides explore the influence a male has on the schoolroom and how it can be perceived by others. Bittner and Cooner found that work forces may experience uncomfortable and uneasy with a schoolroom when kids are trying to be fond and ‘touchy-feely ‘ – non due to the males personal edginess but by the fact that in today ‘s milieus that would be judged by others and seen as incorrect. This provides grounds in favor of female instructors as they are conveyed as loving and lovingness. This stereotype besides differs from sternods article as he argues that adult females are the 1s doing the deficiency of full development chances of kids. Particularly, Sternod looks at male childs larning through a â€Å" masculine nurturing system † where regard is indispensable. Male instructors can utilize different methods of learning kids and have fluctuations in schoolroom behavior direction which differ from females. This method gives male instructors a measure up on females as they have an about point system with male pupils and that the pupils will take to affect -work harder- their male instructor. This strong personal instructor pupil relationship contradicts Cooney and Bittner as they argue that male instructors can non hold a strong relationship with pupils. It is deserving observing that both research workers agree that there is a demand for more male ‘s instructors within the learning profession. They merely somewhat differ on the methodological analysis in which should be set in topographic point to further better male standing in the schoolroom and for the development of kids.DecisionA male influence within the learning profession decidedly has an impact on how kids are educated, the manner kids are educated and the effectivity of schoolroom behavior direction. Without surrogate, new methods of educating our immature people there would be a deficiency of effectual instruction manners that push and develop kids to endeavor to what they can go. A male function theoretical account is critical in guaranting that kids understand the difference between muliebrity in being a miss and maleness in being a adult male. As it is chiefly female instructors in early phases so kids develop more feminine properties and hence deficiency in maleness which is particularly refering for immature male childs. If there was no male presence so at that place would non merely be a deficiency of confident important figures but there besides would be an underlined defect in a kid ‘s gender stereotype instruction. A adult male in a schoolroom gives kids a modern point of view that kids aspire that anyone can make anything they want – non all instructors are females, non all pilots are male. There is grounds that supports males have a better controlled schoolroom with kids holding a inclination to hold better behavior in the pretension of a male. It could be the fact that kids are scared to how a male may respond to bad behavior or it could be due to the regard that the kids have for the pedagogue. Young boys normally behave better around older males as they are seeking to affect them and derive regard. Personally, I think that without males in the instruction profession there would be a batch less compassionate and credence within this modern, of all time altering epoch. Male teacher partly maintain kids up-to-date with altering tendencies within society and hence do the coevals of tomorrow more diverse and accepting. Besides without the first male instructor to animate the following coevals at that place would n't be draw a bead oning instructors such as me.

Bellboy Case

It is essential to first have general understanding of the Terms Bellboy. This name is generally associated with a person whose task is to run errands and sometimes help guests with baggage in hotels. The Bellboy often connected with question; what happened to the dollar, is a case that has been used by scholars to explain and make their ideas more sellable and attractive to their readers and scholars in their scopes of study.Three men of Italian decent also referred to as farmers by profession are said to have visited a foreign country and in the process the need to procure boarding facilities arose.It was in that way that these three gentlemen found themselves in a hotel where they wanted to hire sleeping rooms. After a $30 agreement for the three men they agree amongst themselves that each should give $10. And so they did. Later the hotelier decides to charge twenty five dollars. It is here that we here the bellboy mentioned first as the story continues. The issues arise when the hotelier decides to refund back the excess five dollars back to the three gentlemen. Not knowing how to divide five dollars among three men he decides to keep two dollars for himself and give each-gentle man a dollar as a refund.This is where after reading the story one notices the trick. One,after careful analysis of the story notices that a dollar will end-up being un-accounted for-thus posing the question of what happened to the dollar? The survey as presented is good since it provides readers with deep explanations of the field’s theory populated with daily cases. The case study here presents research marketing, the process of it and also explains the problem in its expository chapters. The general research work design is well reviewed, another plus for the use of the designed data collection forms and methodologies.The authors employ Data collection and exemplary designs in their conclusion of the case-study besides conducting a clear interpretation of facts and analysis . Churchill and Dawn chose to concentrate abstractly on objective support systems and information operations and more specifically to helping information seekers recognize a task easily, put it in order and ask for the opinion of those empowered to make judgments. The appropriateness of the Bell boy case cannot be overemphasized in the way it is used by the authors as a central influence point on the report and generally all over the books.Seemingly intended for grounding the foundations of marketing research, the Bellboy case-study encourages readers to think creatively beyond the scope. Maybe the greatest achievement by both Churchill Gilbert and Dawn Lacobucci lies in the simplicity of the case-study. Being a widely comprehended story, its understandability goes unquestioned. With good understanding, the interpretation follows with ease. On the same note the authors provide readers with a wide variety of professionalism which is exemplified using the Bellboy case-study.In the aut hor’s view, this is the best case scenario to give a reader a full comprehension of the subjects under discussion. Through the use of a highly comprehensible case-study, the authors take readers through nearly all stages of successful marketing and even more conveniently how to make them all work in practical marketing. Gilbert Churchill and Dawn Lucobbaci provide the reader with both theoretical and analytical works. The simplistic case-study, the Bell boy clearly indicates how the study gives basic ideas in some areas.Here too, the marketing researcher is provided with all insight with the requirements of the mathematical skills for the market researcher. By being thorough in explanations of concepts and ideas-both simple and complex, the student or learner is saved from extremes of abstract assumptions and misleading generalizations. The Bellboy case though simplistic in appearance helps the learner to develop creativity and analytical skills which are greatly essential to a marketing research both academic and corporate.Through the case-study the Bellboy the authors bring to focus articles across a broad range of marketing specialties, including consumer behavior, others such as retail tracking, merchandising, retailers and even analytics. The case study The Bellboy brings into clear focus high quality, theoretical and applied research in the areas of marketing and market research. The case study highlights academically oriented research work often focusing in on market orientation and even counter analysis.The analysis provided by the authors provides tips which would provide marketing research-based debates on market topics such as customer retention methods, product comparison and customer satisfaction. The importance of this case study; the Bellboy, cannot be overemphasized as put across by the authors. In a general view, this case provides us with information, intelligence on competition and market research as well as industry trends. Therefore , this is a most appropriate case-study in terms of relevance and objectivity.The text has undergone too much transition that some of original ideas may have acquired new dimensions. To a reader who is new, the case-study may be limiting in the sense that the additional ideas may not have existed in earlier editions. Across all the nine editions, there is a noticeable variation in the way the Bellboy Case is evaluated. This means therefore that a first time reader of a particular edition would miss out on ideas in another edition which he/she is not acquainted with. The Bellboy Case does not look very convincing with regard to some specific topics dealt with in the text.There lacks direct relevance between the topic Role of Marketing and the selected case-study Bellboy. This particular limitation can be cited in several other sub-topics including: Problem Formulation, in the introductory part one. Descriptive and Causal Research Designs in Part two, Standardized Marketing Informatio n in part three. Designing the Questionnaire or Observation Form and The Basics of Measurements all from part three. The simultaneous analysis of multiple variables in part five reveals some remote relevance to the Bellboy case study in part six of the text.Other limitation besides the one of relevance is the overuse of the particular case-study. Though creative and at the same time entertainment, this particular problem of overuse leads to an adventurous reader to a limitation of scope when it comes variety. A good reader no doubt feels limited in the choice of examples used. To some readers the Bellboy Case of what happened to the dollar as given by Churchill and Dawn may appear frivolities and therefore fail to exude the necessary seriousness intended by the authors of the text.In his review of the text, (Brown, 2005) is lf the opinion That being too specific in the use of the Bellboy Case Study limits the number of professionals who can use the book to mostly only trained resear chers are opposed to a general readership or the business community. A reader may question the up-to-date coverage of topics intended by the authors with regards to the Bellboy Case Study. The new or later editions of the text which have expounded information on topic which include sample size issues, forecasted sales and the usefulness of the use of internet may end up confusing the readers as opposed to giving them guidelines.Realizing the Bellboy Case as presented here one at guiltily feels the authors ought to have given several other case studies as a way of justifying their arguments on these topics. As it is a reader and especially one with market research background often feels grieved to only on idea of reference; Bellboy Case Study. At the beginning of the case study, makes a general assumption that most readers are acquainted with Bellboy story. This is generally a wrong assumption since quite to the contrary a good number of marketing research readers may have a problem getting acquainted with the case study.Though this may seem like an easy to overcome limitation, as good authors they should have taken the trouble of classifying to the readers the over told story. Lacking in direct connection too is the relevance of the Bellboy Case to one of the topics given much emphasis. One generally get the opinion that the bellboy case being too general was put out of reference for some extensively covered references such as the use of the intensive in marketing research. The Bellboy Case Study as used in the text leaves the reader and especially a marketing research professional with some unclarified ideas about several of the covered topics.For instance in the topics theoretical applied research in marketing and other areas such as consumer behavior. On the same note discussions on consumer profiles purchasers and retail consolidation effects should have benefited more from the Bellboy case study since one can almost draw direct connection after clearly an alyzing the story. The problem here is that the authors delegated more emphasis on the expository parts of the discussion, leaving this latter one which is equally important shallowly covered. The same problem can be cited on other topics.Such as the discussion on exhaling and analyzing product and market before action taking in market leadership. Weighing both the limitations and strengths of the Bellboy case as used by authors Gilbert A. Churchill and Dawn Lacobucci, one comes to the conclusion that only a good book can exude such a variation of opinionated reviews. Given that the Bellboy case is a fairly well comprehended story the world over, it becomes appropriate in the sense that the business community has a fallback reference point from which views and opinions can be drawn on practical market ideas and opinions.Clearly, the role of marketing research is investigated extensively by the authors leaving a marketing researcher and especially a beginning on with little to grappl e with if any. From tutors point of view the Bellboy case study provides a great teaching aid and resource in explaining marketing research and methodological foundations. The extensive treatment presents a high level in discussion professional codes of conduct and ethics on the part of both authors.All the topics handled in the book presents on acceptable level of relevance to practical marketing an more so the manner in which the authors bring in the Bellboy case study to act as a fall back point of reference for the entire coverage. Most noticeable however are questions one cannot avoid after deciphering the case study especially as used to expound on the usefulness of the internet as a tool of marketing. The question of whether or not the product or service will work online is inevitable. The question of the type and volume of market (product and service) information to include also arises.Coupled with this, the best venue for a product also poses an appropriate question to a ma rket researcher. Finally on this topic the issue of how one should collect the returns – monetary or otherwise becomes paramount. The internet as such becomes an important tool of marketing according to Churchill and Dawn. Here, emphasis is mostly laid on marketing research and information intelligence and sourcing in the internet as tools of marketing. As to the limitations cited here about this particular text, they only remain weaknesses as far as the bellboy case-study is concerned.Viewed in the light of another angle or perspective they could be strengths. It is also important to note here that both Churchill and Dawn have given marketing research and methodological foundations a new dimension and freshness often lacking in many other such texts dealing with especially marketing research. It is finally important to note that every thing has two sides and the strength or weakness only comes in when the pointer is focused on only one of the two sides. Reference Churchill/A . G.
